Introduction of U29 Steel Roof Support Beams Customized U29 Steel Support Mine SupportsU29 Steel Roof Support Beams Customized U29 Steel Support Mine Supports is mainly used for mining tunnel support ,with the features of high pressure steel structure.Steel support is a kind of passive support for coal mine support. It has high tensile strength and compressive strength, and at the same time has good toughness, high supporting force and strong supporting strength. It can be used multiple times and is widely used. Mine U lanes, especially in deep complex roadways and soft coal seam roadways.
Main purposes: mainly used in mine tunnel, mine tunnel secondary purpose of support, as well as the support of the mountains tunnel support.
Main features: pressure, supporting a long time, easy to install is not easy deformation characteristics. zmwm10
